abstract = {Stealth bosons are relatively light boosted particles with a cascade decay
S → A1A2 → qqqq, reconstructed as a single fat jet. In this work, we establish minimal
extensions of the Standard Model that allow for such processes. Namely, we consider
models containing a new (leptophobic) neutral gauge boson Z' and two scalar singlets, plus
extra matter required to cancel the U(1)' anomalies. Our analysis shows that, depending
on the model and benchmark scenario, the expected statistical significance of stealth boson
signals (yet uncovered by current searches at the Large Hadron Collider) is up to nine times
larger than for the most sensitive of the standard leptophobic Z' signals such as dijets, tt
pairs or dibosons. These results provide strong motivation for model-independent searches
that cover these complex signals.},
